Hi Jess,
I spent the whole afternoon investigating the issue and found that the information you sent me applies to the broadcast service (source to wowza) but not for the Publish/delivery service (wowza to visitor).
I disabled all delivery profiles and changing the publish tcp port is OK for all protocols except HLS and applehttp. I even ran a grep script over the kaltura lib files and could not find any expressions with "1935".
As far as I understand, this port setup comes from the Wowza Kaltura module publish call?
My aim is to have the stream content served via http (80) and https (443) ( through our CDN) without altering the standard Wowza and Kaltura settings.
Thanks anyway for all the time spent helping me.
David
